摘要
提出了一种利用分频电路和放大电路实现对LM331构成的频率/电压转换电路输入信号频率范围进行扩展的方法,实现了1 kHz^30 MHz信号的频率/电压转换。该电路结构简单,成本低,功耗小,解决了在许多应用领域待处理信号频率范围较宽而处理不便的问题。
This paper puts forward a divider circuit and amplifier circuit.It can extend the frequency range of the input signal of the frequency-to-voltage conversion circuit LM331 constituted,has realized 1 kHz to 30 MHz signal processing.The circuit has simple structure,low cost,low consumption,and solves the problem that the signal frequency range is too wide to be processed in many applications areas.
